If you’ve ditched the camcorder for a DSLR equipped with video then you already know that flash isn’t much much help when it comes to a dark scene, even if you’re packing a fast lens. The Rotolight ($110) remedies that by providing a convenient on-board ring light packed with 48 LED’s that mounts to either a hotshoe or a shotgun mic to provide you with 50 watts worth of shadowless light. The Rotolight can switch between three color temperatures to match your environment and 6 included filters stow in the light’s rear casing. Go forth, Sundance.
